Senshirou my new OC

This is Senshirou (I don't have a family name for him yet). He is 23 years old and he is student artist. He is one of two OC's who live now in my head. I was drawing him without any reference yesterday night, I think I've changed my sketch 100 times... And I've made shadows with simple airbrush just because I wanted to see these picture complete soooooo bad but didn't had much time for extra details...
